Cure UV CIPP Lining Urban Rural Sewer Pipes Repair Cured In Place Pipe Lining Process

UV-CIPP materials for urban and rural sewer networks repair by No excavation

Basic principles

The CIPP curing method is known in English as cured-in-place pipe. Its principle is to form a complete and new pipeline with structural strength inside the existing pipeline through a certain process.

UV-CIPP, as a process of in-situ curing method, is used for Trenchless repair of underground municipal drainage pipes. The pipe diameter covers DN200-DN1800. The repair length can pass through several sections of manholes at a time, with a length of about 50m-300m. It is mainly aimed at sewage pipes and rainwater pipes and is suitable for various common pipes, such as plastic pipes, concrete reinforced pipes, cast iron pipes, brick pipes, etc.

The basic step is to put the glass fiber liner pee-impregnated with resin into the pipe by dragging, and then irradiate it with ultraviolet UV equipment to make the resin produce a photochemical reaction, quickly cure and harden, and complete the repair.

Daoyunai Energy Saving Technology Limited has been committed to manufacturing trenchless CIPP UV cure systems with liners and CCTV inspection crawlers for underground pipelines to service customers all over the world.

The product range covers four series and more than 20 models in the underground pipeline trenchless repair industry:

1. UV curing and repair integrated system D919: LED lamp curing and high-voltage mercury lamp curing.

2. UV cure liner: from diameter DN200 up to DN1800

3. Hot water cure liner: impregnated liner to invert by water gravity and cure by hot water

4. Pipeline inspection robots crawler D18 and D18s: CCTV video inspection of pipeline defects

5. Pipeline periscope D16S: quickly  view the internal defects of the pipeline

Headquartered in Shanghai, Daoyunai has a number of independent intellectual property rights and also has a manufacturing base and R&D and testing center in Suqian City, Jiangsu Province, covering an area of more than 35000 square meters, which fully implements the international quality management system.
